Force Update ESCD:
If you want to clear ESCD data next time you boot up, and ask the BIOS to reset the settings for the Plug
& Play ISA Card and the PCI Card, select Enabled. But the next time you boot up, this option will
automatically be set as Disabled.
NOTE: The ESCD (Extended System Configuration Data) contains the IRQ, DMA, I/O port, memory
information of the system. This is a specification and a feature specific to the Plug & Play BIOS.
Resources Controlled By:
When resources are controlled manually, assign each system interrupt as one of the following types,
depending on the type of device using the interrupt:
Legacy devices compliant with the original PC AT bus specification require a specific interrupt. PCI PnP
devices comply with the Plug and Play standard, whether designed for the PCI or legacy bus architecture.
Two options are available: Auto (ESCD)  Manual. The default setting is Auto (ESCD). The Award
Plug and Play BIOS has the capability to automatically configure all boot and Plug and Play compatible
devices. If you select Auto (ESCD), all of the interrupt request (IRQ) fields become unselectable, as the
BIOS automatically assigns them.
 IRQ Resources:
If you have trouble in assigning the interrupt resources automatically, you can select Manual to set which
IRQ is assigned to which PCI Device or Reserved it. See the screen shot below.
